lily invention relates to the class of metal fence posts that are objectionround tapered metal fence post,

To obtain the maximum of eficiency from amountof metal in a driven post it is not only necessary to have strength, good anchorage and good facing to steady the post, but easy driving, so that the top of the post will not buckle when being driven" All round tapered posts have a larger di unieter at their lower point; consequently, when driven will cut a larger section of soil than can freely enter the smaller diameter T'Q the post above. As a result, the post con- ..ues to drive harder, as it enters farther the ground, the operator naturally using use force as the post resists, resulting in the top or the post becomingbent and buclrled iuider the heavy blow oil. the driving hammer. By making the bottom of the post in it shape, there is very little resistance to driving, in fact nothing but the thin edge of the metal, there being no packing of the soil until the post has entered the ground to the point of the beginning of the round portion. The soil will begin to pack at this point, and the few inches of farther driving will pack the soil in thell near the ground line, making the post steady by filling out the vacancy which issso objectionable in the round tapered post. This vacancy occurs in a roinid tapered post,.due to the fact that a smaller diameter of the post occupies a space a oi: a size to accommodate the larger diameter of the post at the lower endthat is, the end which first v thermore, while this U-shaped bottom will "rive easily, it will not pull up easy, as the f iction and packing of the soil inside of: the the U to retain the soil when being id up,

It is intended, when the post is in the ground, that it shall be seated, as shown. in Fig. 1, a, with the ll-shaped portion entirely beneath the surface of the ground, as indicated at 12. The post may be formed from the same blank as used in. forming the ordinary tapered tubular post, the mechanism employed, however, being so arranged that the blank is left t shaped at its lower end.

Such posts are intended to be driven in distinction from such posts which are located in a hole in the ground and the earth filled in therearound. By making the bot tom of the post in U-shape, t e driving re" sistance is very small, there, being no tend- However, as the post has entered the ground to nearly the point indicated in Fig, 1, the soil. will begin to pack in the contracted portion thereof, the last few inches of driving being relatively hard.
